缅甸重楼的植物形态与化学成分特征

Morphological characteristics and chemical characteristics of Paris birmanica

目的调查缅甸重楼的资源分布及其化学成分。方法野外调查缅甸重楼的植物资源,采集样品并采用HPLC法分析其化学特征。结果在云南省高黎贡山发现了缅甸重楼Paris birmanica(Takht.)H.Li&Noltie的新分布,对其形态特征进行了详细记录;HPLC法检测表明其化学成分主要为薯蓣皂苷和偏诺皂苷。结论本次调查发现了缅甸重楼的新分布记录,首次分析了其化学成分,丰富了缅甸重楼的研究资料。

OBJECTIVE To investigate the distribution of Paris birmanica （Takht.） H. Li ＆ Nohie and to analyze its chemical characteristics. METHODS The field investigation of distribution of P. birmanica was carried out. Samples were collected and its chemical characteristics were analyzed by HPLC. RESULTS A new record of P. birmanica was found in Gaoligong mountain of Yunnan province. This research described its morphological characteristics in detail. HPLC analyses showed that the chemical constitu- ents were mainly dioscin saponins and pennogenin pennogenyl saponins. CONCLUSION The distribution is a new record of P. birmanica, and its chemical characteristics are analyzed for the first time. This work enriches the study information on P. birmanica and has important significance in the study of Paris of China.
